Product Description
JSZF-10G voltage transformer:

3kv - 11kv Indoor Anti Resonance Voltage Potential Transformer

General:
1. JSZF-10G voltage transformer is of epoxy resin cast semi-enclosed structure,
2. It is used in 10KV and below, 50Hz power system for electrical metering and relay protecion.
3. It has harmonic vibration resistant function
4. It combines single-phase earth fault and earth protection

   Technical parameters: Maximum accurate: 0.2 level
Limit capacity: 200*3VA
This type voltage transformer is an anti-ferromagnetic resonance voltage transformer after the three-phase five-voltage transformer, in order to eliminate the scourge that a lot of ferroresonance burning occur because of power system grounding in various degrees. This product is a semi-closed maintenance-free product made from epoxy.
Brief Introduction
This VT is cated in epoxy resin,insulating and semi-enclosed. It is used in indoor electric power system of rated voltage 10kV and frequency 50Hz for electric measuring and relay protection.It can resist resonance,and single phase earthing fault can do very well with earthing protection.

This type voltage transformer used in the system, each unit has four casting body, metering parts is three voltage casting body in the three-phase core columns, anti resonant part is installed in the another Hollow Sq type iron core. When it's normal operation, the neutral point to ground voltage is zero. anti-resistance part secondary output voltage is zero too. But While one phase short circuit to earth, anti-resistance part secondary side (da-dn) will produce 100V voltage,drive the Relay action, cut off the power supply. The neutraI point taken step of harmonic elimination, make the product does not need more harmonic elimination or damping grounded protected mode that can running safety in the grid, and can running in the Single-phase grounding fault circuit long time.
 
 
 Technical Data
1. The voltage transformers are in accordance with IEC186 and GB1207-2008 "potential transformer" standards;
2. Power factor of load: COS  =0.8(lagging);
3. Surface creepage distance: the product accords with the request of class ||
